Can people pleeze help me do this problem!!!!!!!!!!!!!!!!
Solve for x in the following formula.
y = (n/a)(a + x)

This is an equation in two variables x and y, so one needs two equations to solve for x or y. However, x can be expressed in terms of y as follows:
y = (n / a)(a + x)
y = (n / a)a + (n / a)x
y = n + nx / a
ay = na + nx
nx + na = ay
nx = ay - na
x = (ay / n) - a

Divide (or multiply) to get a + x.
Subtract a.

y = (n/a)(a + x) multiply both sides by a/n
ay/n=a+x subtract a from each side
ay/n-a=x or
x=ay/n-a=a(y/n-1)

multiply the two quantities, so you have:
y=(na+nx)/a
multiply a from bote sides, so you have:
ya=na+nx
subtract na from both side, so you have:
ya-na=nx
divide n from both sides, so you have:
x=(ya-na)/n

mult both sides by a/n
(a/n)y=a+x
(a/n)y-a=x

y = (n/a)(a + x)
ay = n(a + x)
(ay)/n = a + x
x = ((ay)/n) - a
x = (ay - an)/n
x = (a(y - n))/n
x = (a/n)(y - n)
ANS : x = (a/n)(y - n) or (-a/n)(n - y)

y/(n/a)-a=x y divided by n/a - a = x
